Since No Second Prances Trixie became a recurring character and minor protagonist, usually seen with Starlight_Glimmer.

She tends to speak in the third person and refers to herself as "The Great and Powerful Trixie" and variants of it. Though despite being a unicorn and possessing some magical prowess, she instead performs stage magic, mainly sleight of hand and parlour tricks.

In the fandom. Trixie is sometimes considered to be Transgender. She was originally written and conceptualized as a male until being changed to female at the last second. She originally had a singular eye dot in each eye. Which only stallions had.
